Tubulidentata are characterised by their teeth which lack a pulp cavity and form thin tubes which are continuously worn down and replaced.
The hyraxes are any of four species of fairly small, thickset, herbivorous mammals in the order Hyracoidea.
The order Primates contains humans and their closest relatives: lemurs, lorisoids, tarsiers, monkeys, and apes.
The lagomorphs comprise two families, Leporidae (hares and rabbits), and Ochotonidae (pikas).
The order Erinaceomorpha contains a single family, Erinaceidae, which comprise the hedgehogs and gymnures.
The bats' most distinguishing feature is that their forelimbs are developed as wings, making them the only mammals capable of flight.
